Regardless of how on-trend your decor was when you initially adorned your apartment, it's only a matter of time before you feel like your surroundings are outdated. But when a home makeover isn't really in the budget, you might feel stuck with the interior design you've got. You aren't, though. There are tons of budget-friendly approaches to decorating that can spruce up your apartment. Here are just three of them to get the creative juices flowing.

1. Upcycle existing embellishments. If your home-decorating instincts take you to Amazon, let your money-saving instincts lead you to Pinterest instead this time. Look for DIY ways that you can revamp that old coffee table or update worn throw pillows. It might be as easy as picking up a can of spray paint or some ribbon and fabric glue.
2. Frame free pieces of "artwork." You don't have to break the bank on a piece of art in order for it to add something to your room. Prints or photos from magazines and books can have just as great an impact on the aesthetic of your bedroom or living room as expensive artwork. Just find a cheap frame at Target or the thrift store to complement your makeshift work of art.
3. Break out the sewing machine. If you're handy with a needle and thread, there's a lot you can do in your apartment without spending much money. For example, you can easily create new curtains or pillowcases. These are both simple ways to spiff up your apartment that conserve both time and money.

Your entryway has the power to wow or bore guests as soon as they step into your apartment, so it's important to make sure you spend ample time on its interior design. If you're just getting started glamming up your entryway, here are a few tips that should help get the ball rolling.

1. Create a vignette. First things first: find an entryway table. That's where you'll put your hallway vignette. It's part functional, part aesthetically pleasing. Include a tray to collection your keys and loose change when you walk in, but also add strictly decorative touches such as candles, flowers, and other odds and ends that reflect your style.
2. Add a mirror. When you're working with a cozy entryway, you can really expand the space (without knocking down any walls) by just hanging a mirror. Find one that fits in with the rest of your aesthetic, perhaps a round, vintage mirror for last-minute touch-ups before you walk out the door, or maybe a more contemporary square mirror if that jives better with your minimalist decor elsewhere.
3. Glam up your walls. Creating a gallery wall is a surefire way to engage your friends as soon as they walk through the door, especially if you create that gallery wall using personal photos in artfully mismatched frames. You can also use mirrors of different shapes and sizes, however, for the ultimate space-creating effect.
4. Throw down a runner. When you're interior-designing, don't forget about the real estate underfoot, either. Spruce up your floor with a chic, colorful runner.

If you have a hallway table or bedroom dresser that could use some sprucing up, the table vignette may be the way to go. A vignette is simply an embellishment that consists of different elements arranged harmoniously, from blooming flowers to vintage picture frames. The exact contents of the vignette are up to you (consider shopping around at thrift stores), but there are a few rules you should follow when you actually go to create the vignette. Here are four of the top suggestions, gleaned from the internet's interior design experts.

1. Pick a focal point. Before you randomly start arranging knick-knacks on a coffee table, pick an element that will anchor your vignette. For example, it might be a vintage vase filled with flowers or artsy twigs. It could be a pretty picture frame with a personal photo or postcard. Regardless of what it is, make sure the focal point meshes with the colors and style of the rest of your home.
2. Let light win over dark. If you don't already have a focal point in mind, consider using a cool lamp. When creating a vignette, it's imperative that you put it somewhere where the light can accentuate it—and what better way to do that than to make the light a part of it?
3. Use the rule of threes. Interior design experts often adhere to the rule of threes, which essentially states that when grouping design elements, you should opt for odd numbers over even numbers. It creates a focal point that naturally draws the eye.
4. Create depth and texture. You should also vary the arrangement of your vignette elements in order to intrigue onlookers. Instead of placing each piece in a straight line, pull some forward and push others back. Pick candlesticks or books of varying heights. Choose different textures. This will keep your vignette interesting and eye-catching.
